Only one way to save the oceans

Some people think we can keep extracting fossil fuels and later use some techno-fix to extract the carbon back out of the atmosphere.

Researchers in Germany have found that even if we did that, the fact that the oceans absorb CO2, then transport it to the deep ocean, means that the oceans would stay warmer, and more acidic, for thousands of years. The consequences for marine life could be catastrophic.
